The Singing Tube is a great science demonstration used to teach students about sound waves, as the piece of metal pipe is magically made to sing. Since this demonstration requires the use of fire (a propane torch), it must be done by an adult… with a child-like enthusiasm for making science fun.
- Piece of metal pipe about 24 inches long
- 4 inch square piece of metal screen mesh (sometimes called gauze)
- Propane torch
